<Image>.DrawArc (Function)

In french: <Image>.DessineArc

Draws a circle arc or an ellipse arc in an Image control.

The arc is drawn counterclockwise.

Example

// Draw a light yellow arc of circle in IMG_MyDrawing
IMG_MyImage.DrawArc(10, 10, 50, 50, 20, 20, 40, 50, LightYellow)

Syntax

<Image control>.DrawArc(<X1> , <Y1> , <X2> , <Y2> , <X3> , <Y3> , <X4> , <Y4> [, <Line color> [, <Line thickness>]])

<Image control>: Control name

Name of the Image control to be used.

<X1>: Integer

X-coordinate (in pixels) of the upper-left corner of the rectangle containing the circle.

<Y1>: Integer

Y-coordinate (in pixels) of the upper-left corner of the rectangle containing the circle.

<X2>: Integer

X-coordinate (in pixels) of the lower-right corner of the rectangle containing the circle.

<Y2>: Integer

Y-coordinate (in pixels) of the lower-right corner of the rectangle containing the circle.

<X3>: Integer

X-coordinate (in pixels) of the starting point of the arc.

<Y3>: Integer

Y-coordinate (in pixels) of the starting point of the arc.

<X4>: Integer

X-coordinate (in pixels) of the end point of the arc.

<Y4>: Integer

Y-coordinate (in pixels) of the end point of the arc.

<Line color>: Integer or constant (optional)

Color of the arc of circle. This color can correspond to:
an RGB color (returned by RGB),
an HSL color (returned by HSL),
a WLanguage preset color,
If this parameter is not specified, the line color:
is Transparent if <Image>.Pen has not been used beforehand,
corresponds to the color specified in the last call to <Image>.Pen.

<Line thickness>: Optional integer

Remarks

Coordinates of the arc

If the start and end points are not located on the border of the circle (or on the border of the ellipse), the point taken into account corresponds to the intersection between the circle and the line that joins the specified point and the center of the rectangle (which means the center of the circle).

The origin used to calculate the coordinates corresponds to the upper-left corner of the image (coordinates: (0,0)).

Drawing a solid figure

To draw a solid figure (a full arc), use <Image>.DrawChord or <Image>.DrawSlice.
